My new PC won't turn on all a sudden

[kennyk241241]

I just built my new PC and in a day, the PC just won't turn on. I think it might be because I had my power supply on while I was plugging in the rgb led strip to the jled1 pins. Do you guys think this was the reason why my motherboard doesn't work anymore? I've tried pressing the power button multiple times and it still doesn't turn on. (I'm a beginner so I clearly didn't have a clue what I was doing).

Basically, when I press the switch nothing turns on. When I turn on the power supply, the small white led on the gpu turns on but that's about it. Nothing else happens, no fans spinning or anything. The mother board Ez Debugger Led don't turn on either.

I tried clearing CMOS but i dont think if i did it right or not.
